In the context of the current increasing global complexity, this paper points out that this kind of productive factor-based spatial logic not only has structural deficiencies, but also potentially brings about the environmental, economic, social, and political risks in multiple dimensions as follows: first, the crises in regional resources and environment due to the market distortion of productive factors; second, the disappearance of industrial growth impetus due to the investment preference to land urbanization; third, the social polarization caused by the incomplete urbanization of immigrates; fourth, the overdraft of government credit as a result of the unbalanced urbanization of population, industry, and land. Under such a circumstance, the paper proposes a transition of China's existing urbanization policies, so as to achieve the objective of sustainable urbanization in the future.展开更多

文摘China's rapid urbanization in the past 30 years can be abstracted as a spatial-temporal product of the socio-economic mechanism relying on productive factors, which represents the sustained dynamics from labor demographic bonus to land capital discount.
